Kammerköhralm, Kendlbach Fm, Sample 2 (Triassic of Austria)

Where: Austria (47.6° N, 12.6° E: paleocoordinates 31.0° N, 16.9° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Tiefengraben Member (Kendlbach Formation), Rhaetian (208.5 - 201.3 Ma)

• The distance given is from the base of the Kendlbach Fm.

• bed-level stratigraphic resolution

Environment/lithology: marine; brown mudstone

• Gray, brown to yellow mudstone of the remainder of the lower Tiefengraben Member (named locally as Grenzmergel).

Size class: macrofossils

Collection methods: bulk, mechanical,

• A majority of sampled horizons were collected in situ from 1 to 2 m2 bedding plane surfaces and subsequently identified and tallied in the field with representative slabs returned to the laboratory for further mechanical preparation and study. Individual shell beds were consistently ,1 cm thick and were treated as occurring on a single bedding plane. Specimen counts for shell beds are species abundances based on individual specimens per standardized surface area (1 m2).
